Abstract
Group photographs are continuously taken with the same background, whereby at least two image frames are produced. A position of a face of each person is detected from each image frame. A combination weighting function w[p](x, y) is set such that, on the basis of the face detected in one of the two image frames, combination weights of pixels of the said one image frame to corresponding pixels of the other image frame are set, which combination weights decrease with increasing distance from the face of the person in said one image frame. The pixels of the said one image frame are laid on the corresponding pixels of the other image frame based on the combination weighting function w[p](x, y), whereby one composed image is produced.
Claims6
An image composing apparatus comprising:
- an image pick-up unit for continuously taking group photographs with the same background to produce at least two images, wherein the group photograph includes plural persons;
- a feature detecting unit for detecting a position of a feature portion of each person included in the group photograph from each of the two images produced by the image pick-up unit;
- a weight setting unit for, on the basis of the position of the feature portion in one of the two images detected by the feature detecting unit, setting combination weights of pixels of said one image to corresponding pixels of the other image, which combination weights decrease with increasing distance from the position of the feature portion in said one image;
- and
- an image composing unit for overlaying the pixels of said one image on the corresponding pixels of the other image in accordance with the combination weights of said one image set by the weight setting unit to produce a composed image.
A computer readable recording medium to be mounted on an image composing apparatus, wherein the image composing apparatus is provided with a computer and an image pick-up unit for continuously taking group photographs with the same background to produce at least two images, wherein the group photograph includes plural persons, the recording medium having recorded thereon a computer program when executed to make the computer function as means comprising:
- a feature detecting means for detecting a position of a feature portion of each person included in the group photograph from each of the two images produced by the image pick-up unit;
- a weight setting means for, on the basis of the position of the feature portion detected in one of the two images by the feature detecting means, setting combination weights of pixels of said one image to corresponding pixels of the other image, which combination weights decrease with increasing distance from the position of the feature portion in said one image;
- and
- an image composing means for overlaying the pixels of said one image on the corresponding pixels of the other image in accordance with the combination weights set by the weight setting means to produce a composed image.
